The West End of London confusingly actually refers to an area of central London (rather than West London) and includes a number of west postcodes (zipcodes) e.g. W1, WC1 etc.

Hatton Garden is in the EC1 postcode and is NOT in the West End. Old Bond Street is:

“The northern end of Old Bond Street, in particular, is also notable as one of the world’s greatest concentrations of outlets of upmarket jewellers, to the extent that presence on the strip may now be regarded as de rigueur for any brand wishing to proclaim the highest international standing.”

A six usually refers to a top of the line Mercedes S Class (i.e. an S600) although it could refer to a BMW 6 series coupe. With the Maybach no longer in production, the S-Class will be the highest end sedan produced by Mercedes Benz.

I read “riding… like this bitch for sale” as meaning it’s showroom clean.
